Configuring Permissions

You have gone through the steps necessary to set up a shared folder, publish it to Active
Directory, and set it up for offline access. Now you will see how you can protect these files
and folders by using permissions.
You can secure folders using permissions in two ways, and you can secure files in one
way. You can set up permissions and security through NTFS or through sharing.

Understanding NTFS
NTFS is an option that you have when you are formatting a hard drive. You can format a
hard drive for a Microsoft operating system in three ways.
■ File Allocation Table (FAT) is supported on older operating systems only (Server 2003,
Server 2000, XP, and so on).
■ FAT32 is supported in Windows Server 2012 R2.
■ NTFS is supported in Windows Server 2012 R2.
NTFS has many advantages over FAT and FAT32. They include the following:
Compression Compression helps compact files or folders to allow for more efficient
use of hard drive space. For example, a file that usually takes up 20MB of space might use
only 13MB after compression. To enable compression, just open the Advanced Attributes
dialog box for a folder and check the Compress Contents To Save Disk Space box
(see Figure 4.2).

Quotas Quotas allow you to limit how much hard drive space users can have on a server.
Quotas are discussed in greater detail in the section “Configuring Disk Quotas.”
Encryption Encrypting File System (EFS) allows a user or administrator to secure files
or folders by using encryption. Encryption employs the user's security identification
